章系字(照系三等字)与端系字、见系字等皆有谐声关系，且在中古多变为齿音，分化条件复杂，所以，在章系字的归属问题上有两派意见：章系归端，章系与端系相通而不相同。究竟孰是孰非呢？有四点可以证明后说更有道理。一是章系归端论者考证方法有问题，二是古文献材料不足以证明两系读音相同，三是口语材料——现代方言中章系、端系分别明显，四是章系归端则音理难以解释清楚。 Zhang Department of the word (according to the third-class characters) and the end of the Department of words, see the Department of words and so on are all harmonic relationship, and in the Middle Ages change to tooth sound, differentiation conditions are complex, therefore, Opinion: The chapter is the end of the chapter, the chapter system and the end of the line and not the same. What is right or wrong? There are four points to prove that makes more sense. First, the chapter of the end-of-the-line research methods have problems, and second, the ancient literature is not enough to prove the same two-system pronunciation, the third is the spoken language materials - the modern dialect in the chapter, the end of the line were distinct, the fourth chapter is the end of the Sounds difficult to explain clearly.
